My reasoning was:

I would have put it somewhere else, but there is nowhere else to put it.
Making a new library for this one file seemed like overkill.
Finally, there is already stuff in libiberty not related to
portability.  E.g., hashtab or the demangler.

I usually do that to, but I wanted this change not to affect the
contents of the defined enums.

Yeah, I didn't consider that.

I guess I can just put the whole DW_TAG_ prefix in there.
That isn't a big deal.  Or if you have some other suggestion, I can
implement it.
